Continuous-time quantum walk spatial search on the Bollobás scale-free network
Tomo Osada, Bruno Coutinho, Yasser Omar +3
The scale-free property emerges in various real-world networks and is an essential property which characterizes the dynamics or features of such networks. In this work we investiga…
Decoding Quantum Error Correction Codes with Local Variation
Michael Hanks, William J. Munro, Kae Nemoto
In this paper we investigate the role of local information in the decoding of the repetition and surface error correction codes for the protection of quantum states. Our key result…
Active topological photonics
Yasutomo Ota, Kenta Takata, Tomoki Ozawa +6
Topological photonics has emerged as a novel route to engineer the flow of light. Topologically-protected photonic edge modes, which are supported at the perimeters of topologicall…
Ballistic hot-electron transport in a quantum Hall edge channel defined by a double gate
Shunya Akiyama, Taichi Hirasawa, Yuya Sato +3
Ballistic transport of hot electrons in a quantum Hall edge channel is attractive for studying electronic analog of quantum optics, where the edge potential profile is an important…
Effective Compression of Quantum Braided Circuits Aided by ZX-Calculus
Michael Hanks, Marta P. Estarellas, William J. Munro +1
Mapping a quantum algorithm to any practical large-scale quantum computer will require a sequence of compilations and optimizations. At the level of fault-tolerant encoding, one li…
Device-independent Randomness Expansion with Entangled Photons
Lynden K. Shalm, Yanbao Zhang, Joshua C. Bienfang +12
With the growing availability of experimental loophole-free Bell tests, it has become possible to implement a new class of device-independent random number generators whose output…
